msnwasm Application filed April 5, 1922. Serial 1%. 549,862.

Be it known that I, WALDEN T. RownLL,

'a citizen of the United States of America,

residing at Chicago, in the county of Cook and State of Illinois, haveinventedia, certain new and useful Improvement in Dish- Washers, ofwhich the following is a specification.

- This invention relates to that type of dish washers in which hot wateris sprayed upon the dishes, etc., stacked within a containing casing to.effect a gradual cleaning of the same, the waste water flowing awayafter it reaches the bottom of the casing. The object of the presentimprovement is To provide a structural formation and combination ofparts in a household dish washing apparatus, by means of which aninitial flow or spray of clear hot water is attained to effect apreheating of the dishes and softening of the impurities thereon, with asucceeding flow or spray of mixed hot water and cleaning compound toeffect a cutting up or removal of said impurities, and with a final flowof clear hot water to com lete the removal of the impurities. Suclloperations succeeding each other automatically and without any attentionon the part of the housewife, all as will hereinafter more fully appear.

In the accompanying drawings Fig. 1, is a longitudinal sectionalelevation of the apparatus.

Fig. 2, is a horizontal section on line 2, 2, Fig. 1.

on line 3,-3, Fig. 1. I

Fig. 4, is an enlarged detail longitudinal section of the automaticfeeding attachment for the cleaning compound.

and 5 a com anion solid head or trunnion arranged in ongitudinallyaligned relation and revolubly mounted in bearing bushings 6 and 7attached to the central portions of the end walls of the casing 1adjacent to the Fig. 3, is a transverse'sectional elevation bottom ofthe same as shown. In the present construction the tubular trunnion 4extends a distance outside the casing 1 and is provided with anoperating lever or handle 8, by which oscillatory "movement can beimparted to said trunnion and its associated parts by hand and asrequired.

9 designates a tubular member or manifold arranged longitudinally in theupper ,portion of the casing 1, and adapted to have movement in atransverse direction by connections with the trunnions 4 and 5 asfollows:

10 designates a tubular member or pipe section connecting the tubulartrunnion 4 with one end of the manifold 9.

11 designates a companion member, which may have a solid formation,connecting the other end of the manifold 9 with the other trunnion 5.

12 designates a-series of jet members,

preferably of the rose head type shown, connected to the manifold 9 inlongitudinal spaced relation, and adapted to effect a downwarddischarge, of the hot water in different directions, so that in actualuse all sides ofthe dishes will be reached and elfectively cleaned.

13 designates a dish containing tray-or holder, of a rectangular shapeand arranged in a removable manner inthe bottom portion of thecontainer 1. The tray 13 is of a skeleton wire formation and has aplurality of Lshaped wire partitions 14 arranged in longitudinallyspaced relation to each other at the respectlve sides of the tray, andwhich in connection with the upwardly dished wire bottom 15' of thetray, provide an effective support for lates,

dishes, etc., in vertical separated re ation during the washingoperation. a

' 16 designates an open top holder of orificed material arrangedtransversely at one end of the tray 13, and adapted to receive forks,knives, etc., to be washed.

17 designates a vertical rack of a rectangular yoke shape as shown, thevertical posts of which removably fit in socket mem-' bars 18 fixedlyattached to the tray 13 as shown and having holding hooks 17 for cupsand the like. The construction is intended to permit of a convenientremoval of the filled tray 13, past the above described manifold and itsconnections, by a preliminary removal of the rack 17 just described.

The material part of this invention in-' volves means for introducing acleaning compound of soap or the like into the supply of washing waterin the commencement of the o eration, and comprises a construction asollows 19 designates a chambered cap secured to the outer end of thetubular trunnion 4, and provided with a tubular and externally ridgedneck 20 adapted to receive an end of the flexible hose by whichconnection is had with the hot water supply of the building. The passageof the neck 20, is preferably in line with the main passage 21 of saidtubular trunnion 4:, so that the hot watermay 'flow in a direct mannerthrough said trunnion, thence through the tubular member or pipe 10;into the manifold 9 to be discharged through the jet heads 12 upon thedishes operated'on.

.22 designates a container having an entry at'top closed by a cap orcover 23 to admit of convenient introduction of a charge of cleaningcompound, such as granulated soap, tor'use in the dish washingoperation. The container 22' is fixedly secured to a side of the tubulartrunnion 4 and has connect-ions therewith as follows 2d designates ahollow stem arranged vertically inside the container '22, with itspassage connected by an L shaped branch passage 25 with the waterchamber of the cap member 19 aforesaid, while'said hollow stem 24, isformed with a series of lateral orifices 26 along its height fordischarging jets of the hot water into the above mentioned charge ofcleaning compound.

27 designates a perforate partition or grating arranged above the bottomof the container 22 for the support of said charge of cleaning compound.

28 designates an l. shaped passage connecting the bottom of thecontainer 22 with an expanded chamber at the inner end of v the trunniond with which -the tubular memher or pi e 10 has connection.

With t e above described arrangement of I parts, a predetermined chargeof the cleaning compound is placed in the container 22 previous toturning on the hot water supply, after which the hot water is turned onand in the initial portion of the operation, the hot water passingthrough the above 'described passages of the container 22, takes neasarup the cleaning compound, carries it to and mixes it"with the main flowof hot water tom wall formed with a straight way passage for. the hotwater used and unimpeded branch passages between said straight way passae and the container adapted to afiord an in ow of water into the upperportion of said container and an outflow from the bottom of the sameinto the straight way pas sage, a bushing adapted'for fixed attachmentto the casing of a dish washer and forming a support for the aforesaidinlet head, a handle on said head for imparting turning movementthereto, and a sprayer head fixedly connected to said head so as to movetherewith' 2. In a dish washing apparatus of the type herein described,the combination of a water inlet head comprising a closed containeradapted to hold a limited charge of cleaning compound and having adepending bottom wall formed with a straight way passage for the hotwater used and unim peded branch passages between said straight waypassage and the container adapted to aTfi'ord an inflow of water intothe 11 per portion of said container and an out ow from the bottom ofthe same into'the straight way passage, a perforated partition arrangedad- 1acent to the bottom of said container, a bushing adapted for fixedattachment to the casing of a dish washer and forming a support for theaforesaid inlet head, a handle till) MED
